Over 50 million tons of copper slag are produced worldwide annually. Stacking is currently the primary method used to treat copper slag, resulting in resource wastage and environmental issues. Using slag as a raw material in the steel industry is a reasonable solution. However, the presence of nonferrous metals degrades steel performance and …

Slag generating from the basic oxygen furnace during steelmaking is one of the significant solid wastes that has not been recycled due to many physical, chemical, and structural properties. Phosphorous is one of the key yardsticks for recycling the slag as a Ca-rich flux into the iron making process. The recycling of the slag depends on the …

Electrical conductivity of molten slag is an important physicochemical property for designing the refming process in electric smelting furnaces. Though conductivities of many slag systems have been measured, the quantitative relationships of conductivity with slag composition and temperature are still very limited. In this article, …

Typical nonferrous slag contains 30–55% FeO, 30–45% SiO 2, and less than 10% CaO, although variations occur depending on the system in which the slag is formed ( Kokal, 2006 ). Nonferrous slags are sometimes classified as basic, acid, and neutral slag …

Slag is a typical byproduct generated during high-temperature metallurgical processes. It must be treated appropriately to meet the increasingly strict environmental requirements and to realize the economic benefits.1,2 The present topic, "Slag Metallurgy and Metallurgical Waste Recycling," collects eight articles, which demonstrate the …

Copper Slag. Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in embankment applications. Copper slag can readily satisfy the gradation and physical requirements of AASHTO M145. (11) Unit Weight: Copper slag has a unit weight of 2800 to 3800 kg/m 3 (175 to 237 lb/ft 3).

The Ti-slag resulted in the consumption of calcium hydroxide due to its pozzolanic reaction, lowering the indentation modulus and hardness of the C–S–H gel, which could improve the adsorption of HMs and chlorides (Sun et al., 2022b). According to the electric double layer theory, the replacement of Si by Al would lead to the Ca sorption ...

A novel smelting reduction process based on FeO–SiO 2 –Al 2 O 3 slag system for spent lithium ion batteries with Al cans was developed, while using copper slag as the only slag former. The feasibility of the process and the mechanism of copper loss in slag were investigated. 98.83% Co, 98.39% Ni and 93.57% Cu were recovered under …

Labscale freeze layers of an industrial nonferrous slag with Al2O3-CaO-FeO x -MgO-SiO2-ZnO as main components are studied to explore the microstructure and the composition of an industrial freeze lining. The freeze layers were formed by submerging a watercooled probe into a liquid slag bath. The influence of submergence time, of heat …

Mn and Li were selectively extracted from the manganese-rich slag by sulfation roasting−water leaching. The extraction mechanisms of Mn and Li were investigated by means of XRD, TG−DSC, and SEM−EDS. 73.71% Mn and 73.28% Li were leached under optimal experimental conditions: acid concentration of 82 wt.%, acid-to …
